Jianghuai Refine tire model specification is 205/70/R15, focusing on quietness, comfort, and balanced overall performance. The Refine still adopts the front MacPherson and rear torsion beam suspension structure, which is a common suspension type in this class. The tires use the GitiWingro series tires by Giti—a set of tires that emphasizes durability, wet road performance, and low noise. Tire material: The main body of the tire is rubber, and the maximum storage and anti-aging time of rubber, from natural latex to ethylene propylene and nitrile, will not exceed 10 years. The average service life of various rubber products in use is 3-5 years. Tire lifespan: The wear lifespan of tires is 30,000-50,000 kilometers. If the tire has not reached the wear limit and mileage but has been in use for 5 years or has developed a large number of cracks on the side, the tire needs to be replaced.

Our family drives a Refine M4, which originally came with 205/70 R15 tires. Last time when I went to the auto repair shop for tire replacement, the owner emphasized that 205 refers to the tread width in millimeters, 70 indicates the aspect ratio, R stands for radial construction, and 15 is the wheel diameter in inches. In the same series, the M5 commonly uses 215/65 R16, while the newly launched electric version adopts 225/60 R17 low rolling resistance tires. To find out the exact specifications of your car, the most accurate way is to check the sidewall markings by crouching down. For example, my left front tire is marked with '215/65R16 98H'. If considering modifications, it's recommended to maintain the original factory parameters, otherwise the ABS and tire pressure monitoring system might generate errors.

Last time I helped a friend pick a used Refine, I noticed a wide variety of tire models. Older Refine models often came with 205/65 R15 tires, while the current common M3 business version uses 185/65 R15, and the high-end version upgrades to 195/55 R16. Pay special attention to the raised alphanumeric combination on the tire sidewall, and make sure not to mix up the numbers before and after the slash. Once, a neighbor tried to save money by installing the wrong size, and the tire sidewall rubbed against the fender when turning, forcing them to spend more money to replace it. Before changing tires, it's recommended to take a photo of the complete model number on the side of the original tire or check the vehicle nameplate below the B-pillar on the driver's side.

Having repaired cars for over a decade, most of the Jianghuai Refine models I've worked with use 15-17 inch wheels. Early models like the Refine II preferred 205/65 R15, while the current mainstream Refine M series typically comes with 185/65 R15 for base configurations and 215/65 R16 for higher trims. Summer often brings tire pressure issues - remember the pressure label is usually located inside the fuel filler flap or on the driver's door frame, with recommended cold tire pressure of 2.3-2.5bar. When replacing tires, pay attention to speed ratings - for example, S-rated tires with a 180km/h limit are sufficient, while H-rated tires can handle up to 210km/h and offer better durability.

As fleet managers, we uniformly use 215/65 R16 tires for all 20 of our Refine M5 vehicles. This specification is particularly suitable for commercial load requirements, with a load index of 98 representing a maximum single-tire capacity of 750kg. Last year, we experimented with switching to 225/60 R17 tires, which resulted in a 0.8L increase in fuel consumption and were more prone to bulging. Now we strictly procure original equipment tires from Triangle or Giti, with the heavy-duty variants featuring a 'C' sidewall marking proving more durable. Bigger tires aren't necessarily better - the factory-matched specifications provide the most balanced handling stability.

Just took over my dad's 2016 Refine S3, the original 205/55 R16 tires have excellent grip. When checking the maintenance manual, I noticed JAC was quite meticulous, even specifying the spare tire size as a compact temporary T125/90 D16. Once got a nail puncture and went for repair, the mechanic taught me to read the tire date code: the four digits after DOT on the tire sidewall, like 3621 means the 36th week of 2021. Now when replacing tires, just provide the model year and the repair system can automatically retrieve the original specifications, making it hassle-free and accurate.
